Should this go through "if" or not? (C language)

To put it short, the problem is that it's passing through an IF statement when the argument is False.

Questions: is the argument actually false? I am talking about the 2nd "if" from the block below. I used many "or" operand, that's what I am afraid of.

Please, I couldn't sleep last night because of this bug.

if(iNou == (height - 1) ) 
    {
        if(ptMatricePixeliB[iNou][jNou - 1] == 'X' || ptMatricePixeliB[iNou - 1][jNou - 1] == 'X' || ptMatricePixeliB[iNou - 1][jNou] || ptMatricePixeliB[iNou - 1][jNou + 1] == 'X' || ptMatricePixeliB[iNou][jNou + 1] == 'X') 
        {
            return 0; 
        }else 
            {
                return 1; 
            }
    }  

When I used the debugger I got this:

if(ptMatricePixeliB[iNou][jNou - 1] == 'X' || ptMatricePixeliB[iNou - 1][jNou - 1] == 'X' || ptMatricePixeliB[iNou - 1][jNou] || ptMatricePixeliB[iNou - 1][jNou + 1] == 'X' || ptMatricePixeliB[iNou][jNou + 1] == 'X')
